As a leading 3rd party EMC Test Lab, MET Labs maintains a strict ISO/IEC 17025-2005 Quality System. This system includes a set of requirements addressing the subject of traceability of measurement results.

Traceability means that the result of a measurement can be related to a national or international measurement standard, and that this relationship is documented. In addition, the measuring instrument must be calibrated by a measurement standard that is itself traceable.

Traceability is important because it allows the comparison of the accuracy of measurements worldwide according to a standardized procedure for estimating measurement uncertainty.

To guarantee traceability, MET uses measuring equipment that has been calibrated by an accredited calibration laboratory and meets international specifications:

If no standard is available to calibrate a piece of test equipment (e.g. for spectrum analyzers or signal generators), MET uses the equipment manufacturer’s calibration process, per ISO/IEC 17025.

Since the calibration of measuring receivers has caused confusion in the EMC community, CISPR subcommittee A is in preparation of a normative annex to CISPR 16-1-1 (the future CISPR 16-1-6) to better outline the calibration requirements for measuring receivers.

In summary, EMC test results at MET Labs are subject to a strict Quality System that ensures accuracy, repeatability, and traceability. Contact us today for a free quote for your next EMC testing need.
